| photomultiplier housings Optimal performance can be obtained by operating the photomultiplier within an appropriately designed housing. A housing offers the following benefits: • shielding against electromagnetic interference • reduction of the effects of external magnetic fields • incorporation of good high frequency techniques to preserve signal waveforms • stable mounting of the photomultiplier • provides convenient mounting arrangements • exchangeable photomultiplier A photomultiplier housing is a convenient way to achieve reliability of performance. In addition, measurements can be performed immediately after installation. | |||||||||||||||||
| " his amahura describes '.'■(: jNiducLs avaikib to sa! up a detection system with minimum effort: • sockets for mounting purposes and for providing electrical contact to the photo multiplier • voltage dividers to establish the required electrical operating conditions • shielding to reduce the effect of external magnetic fields on the performance of the photomultipller • housings provide a light-tight enclosure, which can include the voltage divider, socket, magnetic shielding, power supply, and signal conditioning electronics • high voltage power supplies • signal conditioning electronics | |||||||||||||||||
| basic photomultiplier configurations The figures below illustrate the basic forms of a detector, figure 1 - illimitée :-e lilic-lornililiplier ■.vi:h socket r-).-:l voltage divider. The voltage divider may either be wired by the user, or supplied pre-wired from Electron Tubes. figure 2 - shows the voltage divider board solderai: draaily to a photomultiplier with a flying lead base. figure 3 - illustrates an integrated module, consisting of a pholomultiplier and voltage divider encapsulated within a metal sleeve. | |||||||||||||||||
| Cooled housings include all of these features but their principal function is to maintain the photomultiplier at a constant, low temperature to achieve: • stability of performance unaffected by changes In ambient temperature • measurement of very weak signals through reduction of photomultiplier background | |||||||||||||||||
